There are two same metals which will be plastically deformed through reducing their cross-section areas. The first metal has a rectangular cross-section while the second one has a circle cross-section. These cross-section shapes will not change during the process. The initial sizes of the cross-sections are listed as below: Rectangular length, mm Circle diameter, mm Initial cross-section size 110x110 16 Deformed cross-section size 50x120 12.6 Which of these samples will be the hardest after the deformation and explain the reason. [hint: the higher plastic deformation has higher hardness]

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
